## Discrepancy

REMOVED PROPELLER TO REPLACE CRANKSHAFT SEAL.  FOUND CRANKSHAFT FLANGE SEVERELY CORRODED.  REMOVED ENGINE FROM SERVICE FOR CRANKSHAFT REPLACEMENT.  ENGINE HAD BEEN OVERHAULED BY AN 'IA' JUST 75 HOURS AND 3 YEARS PREVIOUS TO THIS DISCOVERY.  SUBMITTER BELIEVES CORROSION EXISTED AT THAT TIME.
